FRESH-AIR-TREATMENT APPARATUS.

Specification of Letters Patent.

Application filed May 26, 1908.

Patented March 80, 1909.

Serial No. l85,0'71.

To all whom it may concern:

Be it known that I, Lawrence P. LEON- ARI), a citizen of the UnitedStates, residing at St. Cloud, in the county of Stearns and State ofMinnesota, have invented certain new and useful Improvements inFresh-Air- Treatment Apparatus, of which the following is aspecification.

My invention relates to devices for treating patients suffering fromtuberculosis, pneumonia, anemia, etc., with fresh air.

On Feb. 18, 1908, there was granted to me United States Letters PatentNo. 879,391, for day treatment of patients with fresh air in which onlythe patients nose was covered by the end of the inhaler but he wasrequired to lie in one position to keep the device in lace.

The invention hereinafter described and claimed is particularly designedfor use in treating patients at night and is constructed to inclose thepatients head so that the patient can turn in his sleep and stillreceive the benefits of the treatment.

The construction and operation of my improved apparatus for fresh airtreatment is described hereinafter and illustrated in the accompanyingdrawings in which a room and the patient lying in bed with my improvedapparatus in position, Fig. 2, a cross-section of the joint by which theinduction tube is secured to the window, Fig. 3, a front view, on anenlarged scale, of the diffusing chamber, Fig. i, a side view, Fig. 5,a'longitudinal sectional view thereof, and Fig. 6, a view showing anattachment for sliding windows.

In thedrawings similar reference characters indicate corresponding partsin all the views.

In the form shown in Fig. 1 my device is shown in connection with awindow A having a sliding sash B and a swinging storm sash B controlledby means of a latch C. The device may be attached to the sliding sash orif desired a separate sash D may be used as shown in Fig. 6 and insertedunder the lower sliding sash B or above the upper sash as desired, theposition of sash D being fixed by the height of the window here thewindow is not conveniently placed for attachment of my device it will beapparent-that a hole may be made in the outer wall of thebuild inp; toaccommodate the end of the induction tube and filter, hereinafterdescribed, it not being considered to be necessary to illustrate thisconstruction.

Secured to sash B or D is a plate 1 having' a hole 2 therein opening tothe outer air and with a socket surroundingthe hole to receive thespherical enlargement t on the end of induction tube 6 indicates anotherplate having a hole 7 therein to receive tube 5 and upset around saidhole as shown at S to form a socket to fit the spherical enlargement t.

9 indicates bolts secured to plate 1 having eye-loops 9. and 10 hookedrods mounted on plate 6 to engage said eye-loops 9, the ends of saidrods 10 beingthreaded to receive wine nuts 11. This construction forms aball and socket joint for the receiving end of induction tube 5 so thatthe tube may be adjusted within certain limits to suit the position ofthe patient.

12 indicates a hook secured to the casing of the window A or otherconvenient place and 13 a spring: secured to the hook and to tube 5 tosupport it and still permit movement of the tube to accommodate itselfto the movements of the patient.

The dili'using chamber consists of a cylindrical shaped casing 14fv madeof a heavy air-proof fabric such as canvas and is secured to the innerend of tube 5 by means of a strap 15 run through guides 16 on the upperend of easing l t. The casing 1% is made preferably larger in diameterintermediate of its ends as shown at 17 andhas a hoop 18 secured at thelarge portion 17 and other hoops 19 between the upper end of casing 1and the enlarged portion 17 so as to hold the upper portion of thecasing distended.

20 indicates bands of elastic material secured longitudinally of thecasing between its upper end and enlarged portion 17 and adapted tonormally pucker the upper end of the casing so as to prevent it fromsagging when not fully extended by the position of the patient. A hoop21 is also secured to the lower edge of easing id to hold it distended.

2 indicates a hood secured to the lower edge of casing 14: by means oflacing strings, buttons or other detachable fastenings said hood beingmade of a softer fabric than that of said casing, is opened at the frontas shown at 23 to receive the head of the patient, and has flaps 24:with any temporary fastening means such as button holes and buttons tofasten them across the patients throat. To protect the top of thepatients head from the air the hood 22 is continued inside of the casingas shown at 25 to engage the forehead of the patient.

26 indicates pockets on the inside of the casing 14: to hold resinousmaterial or other medicinal substance with which it may be desired toimpregnate the air.

27 indicates a window of sheet celluloid or other transparent materialto permit the patient to see what is going on around him and 28 anopening containing a gusset 29 and closed by a craw-string 3O engagingbutton 31 or other fastening means to permit the patient to insert hishand and a handkerchief to reach his mouth and nose.

32 indicates a damper in tube 5 controlled by rods or other means 33 toregulate the ingress of air, said rods 32 being arranged conveniently tothe patient as shown in Fig. 1.

The induction tube 5 may be made of any suitable material but I preferto use wood fiber, which is a nonconductor of heat, so as to preventchilling the room.

In order that the air may be cleared of insects, dust, and other smallparticles floating therein before entering the induction tube 5 I securea filter over the mouth of the tube consisting of a strip of wire meshscreen 34 covered by a layer of filtering cloth 35 such as mull or silk.In the drawings I have shown the filter secured by means of bolts 9 tothe outside of plate 1 but any other method of securing it in positionmay be substituted if desired.

Having thus described my invention what I claim is 1. In a fresh airtreatment apparatus, in combination with the window, a perforated platesecured thereto having a socket, the induction tube made of rigidmaterial and having a spherical enlargement on its end to engage saidsocket, and means to secure said enlargement in the socket.

2. In a fresh air treatment apparatus, in combination with the window, aperforated plate secured thereto having a socket, the induction tubemade of rigid material and having a sphericalenlargement on its end toengage said socket, and another perforated plate formed with a socket toengage said enlargement and adjustably secured to the first-mentionedplate.

8. In a fresh air treatment apparatus, in combination with the window, aplate secured thereto having a socket, the induction tube having aspherical enlargement on its end to engage said socket, another plateformed with a socket to engage said enlargement, hooked rods secured toone plate, and rods having eye-loops to engage said hooked rods securedto the other plate.
